I want to say somethings
At first, I compliment Duet of Love & lust, my favorite game at moment. This game is the single what explores two traditional but antagonistic types of NTR: netori (cheating), netorase (hotwifing, sharing). The consent element that players have been asking a years ago to developers is being introduced here. To get any sex scene, you need validation. There is a way where Nat manipulates Ethan, the route where ethan is being cheated behind his back, but most of the routes are consent-based. Decisions are made in conversation, like a couple thing. What we (players) decides at now is: WHO is more engaged, NAT or ETHAN? Who enchourages who? But, both wants to try new experiencies. Keep it. Consent matters. To the DEV: Keep it at now. more fun for the COUPLE (I hope Ethan enjoys it and stay in the same room with Nat when she fulfills his\her fetish).
keep attention to these two things: for every guy Nat gets involved with, she needs to feel a strong sexual tension, but at the same time she needs maintain the love and desire to continue satisfying her husband. 1. Don't commit the same sin as other netorase games ~and even real couples. Don't forget that a good sexual tension is indispensable for good sex, purely casual sex is not so good, EXCEPT IF we are talking about alcohool, pool parties, swing orgies, beach vacations etc. The game can create tension in locals where people becomes horny naturally. 2. Please don’t forget to keep the actual synergy between nat and Ethan. Many games lose performance in the middlegame because the wife corrupts too fast and don’t mind for the husband, after a few experiences. The fun on hotwifing\cuckolding is precisely these twists: the emotional conflict between feelings of love and fidelity for one guy and sexual desire for another, by the girl\the conflict between insecurity and obsession, by the cuck.
These elements are FUNDAMENTALS to an healthy and experienced couple in this lifestyle. Of course, I'm here talking about the routes where consent matters (cuckolding, nat reluctant and others). In the endgame, things go off the rails on some routes and that's a matter for the future, but for now... it would be good to keep things as they are.
Personally, I prefer the route where Ethan encourages his reluctant wife because I think it makes the beginning more coherent (yes, I hope she becomes more independent, but if she was so obstinate at first, she'd look like everyone else's sociopathic wife, a boring cliché). Nat and Jenna have very different personalities. Jenna is a whore, a woman who doesn't submit to any man. She is very self-confident. She is the sociopathic hotwife. But Nat is more shy and reserved. Maybe Nat turns herself into a new Jenna (ntr route), but most of the routes go the other way
To the dev: I don't know what, but one these things os not working well: Ethan was literally a sissy and Darrell had a LOT of influence over the couple. I think a third way would be more fun. This mixture can complicate the relationship too soon.
How resolve this?
Don't forgive, Ethan role is a ultrapositive point of your game. Would be more funny if instead acts like a sissy, Ethan could be enjoy and participate with secondary roles (too fast to need darrell permission). a threesome that turns twosome is funny about penetration, not about all the sex. It means: Ethan should give pleasure to nat too. When Ethan was so insecure, he ended without a role, right?; for other hand, Darrell had too much influence over ethan and nat this update. I prefer if it sounds like ethan and nat see darrell more as a toyboy. I don't know if it was a double problem. Maybe it would be fun If darrell was the lead role, but only if ethan and nat don't lose their sinergy.
2 good scenarios: Darrell lead the threesome, ethan feel insecure, but enjoy it, kiss and suck his wife, clean her pussy, be sucked by her and masturbate himself;
Darrell sounds like a boytoy to the couple. They keep a STRONG sinergy. But during sex, Nat priorize darrell and ethan enjoy it in the same way.
So: who will be the boss during the trio, Nat or Dar?
And about the future of relationships? To keep nat faithfulness, in long term, ethan needs to be more strong than he is now. Cuckolding is play with fire, is corrupting a faithfull wife... this experiences maybe confuse her. Would make more sense if nat was more dependent of Ethan. Maybe ethan BAD sexual performance is not a good idea, i'd like him with a better stamina. Nat having difficultes with cum after darrell is ok, but before... hmm I don't think it will have a happy ending. Ethan needs be a more successful guy and more rich to keep his woman, with his strange fetish. Telationships are like a tug of war and the cuck plays at a disadvantage. You need think about that. Maybe a children is not a bad idea (ethan as the father, of course)
Another point is: Inside cuckolding spectrum there are strong variations. The more common form of cuckolding on videos\cartoons is what called cuckoldry, the hotwife have the reins of the relationship, she is the boss, etc. I'm tired these type of content. But a very popular llifestyle on forums is what called 'vixen-stag', is literally the oppositive a sissy cuckold. In many worlds: A stag is the bossy, he in less dependent of his partner than she is of him. He is a cuck, but he is the boss. He decides when and where. He is smart, persuasive and knows what he wants to do to keep his wife
This game born with multiple proposals, but aparently most people here wants to see nat and ethan enjoying a cuckold relantionship. Particularly, i want play with a self-confidante guy who wants to see his wife fucked by others. I'm replying myself because our protagonists are in a delicate stage now and a wrong step can ruin next stages.
The dev do a good plot at here. It's nice how curiosity turns in desire for both of them. I like to play from the beginning every update because the twists (talking aboout nat), create a lot of sexual tension on me. I hope my advice helps with new perspectives to the middlegame.
